What is a network transceiver and how does it work?

Communication is not only limited to human beings but plays an equally important part when any equipment, systems, latest technologies, or innovations are concerned. Network transceivers are used to communicate by transmitting or receiving information among computer devices. Here is a brief description of what transceivers are and how they work.

What is a transceiver?

The transceiver is a networking device that is responsible for transmitting or receiving signals in a single package. Transceivers are used for wireless communication devices. The signals are transmitted/received through these devices through a cable or optical fiber system. Further, the local area networks (LAN) use transceivers as part of the network interface cards. These devices not only transmit signals through the network wire but also help with detecting electrical signals flowing through the wire. But there are certain networks that need an external transceiver. Also, for devices such as smartphones, or cordless phones, transceivers are found in mobile devices. transceivers are capable of handling analog or digital signals. in places where digital coverage is interrupted or uncertain, however, the transceiver may be able to cater to analog signals as well so that the signals are not lost. 

Moreover, the capability of sending and receiving signals results in making the transceivers expensive. Whereas, mixed analog/digital devices help the users who usually cannot rely on digital coverage specifically in the regions where digital signals are interrupted.

What are the types of Transceivers?

types of Transceivers

There are different types of transceivers that consist of different specifications that are suitable for different requirements of the wireless communication systems;

  • RF Transceivers are designed for baseband modems and routers for analog and digital transmission. and they are also used in satellite communication networks.
  • Optical Transceivers help with converting electronic signals to light signals. These are the high-speed transmission devices
  • Ethernet Transceivers help with connecting electronic devices in Ethernet circuitry.
  • Wireless Transceivers help with combining technology in Ethernet and RF transponders that helps with improving Wi-Fi transmission speed.
  • SFP (small form factor) transceivers are available in different variations of modules including multimode fiber, SX, LX, and BX models.
  • SFP+ Transceivers are the advanced versions of SFP transceivers that can support data rates up to 10GB/s and 8GB/s fiber channels. 

How do Transceivers Transmit and Receive Signals?

There are two ways transceivers transmit and receive signals in two ways;

Half-Duplex transceivers enable the devices to transmit or receive signals. These transceivers can only perform one function at a time. whereas, full-duplex transceivers, the radio transmitter, and the receiver can function in parallel. For instance, half-duplex transceivers are found in walkies-talkies, ham radios, and further single-frequency devices followed by other types that are used in mobile two-way radios. Further full-duplex transceivers are used for satellite networks. The transceiver in satellites is called uplinks whereas receivers are known as downlinks.

Do transceivers need an antenna?

To function, it is necessary for Transceivers to need antennas. It is necessary for transceivers to have an antenna or aerial as they are responsible to establish the connection between radio waves and electric currents and are used with the receiver, transmitter, and transceiver. Hence, antennas are necessary for all the radio equipment that either transmit or receive waves between different locations. Further, it is necessary to note that there are different types of antennas each with different specifications that are suitable for the various types of transceivers. For instance, to receive signals from multiple transmitter locations, a directional antenna will serve the purpose.
